Technical details

This code injection vulnerability exists in OFBiz's widget XML processing and Groovy expression evaluation during screen rendering. An attacker can stage crafted widget XML through a multipart upload and override the mainDecoratorLocation parameter via an unauthenticated JSON request to the manager login route (or the /sfa/control/editPortalPageColumnWidth endpoint), causing the application to load and execute unsandboxed Groovy expressions from the malicious XML. The vulnerability does not require persistence to disk; it exploits the screen loader's live process file descriptor access during upload streaming.
